I did what randys breakin guide says. I put a 100 continuous miles on it after the first 500 and it was very hot after this. I'll try the redline but I don't know that that will solve the problem. Maybe my pinion preload is to tight? But it was within specs? Who know maybe this problem will just correct itself with time.

85 SR5 4runner....Too many hours of work put into it, Hacked, Beaten, and Still running after all I've put it through

87 Turbo Pickup...Bought Her for $500 put another $500 in her and she's running like a dream.
